在全国人民认真学习无产阶级专政理论的热潮中,在庆祝鞍钢宪法发表十五周年的大喜日子里,我厂制造使用了微调铣镗孔工具(图1)。结构原理及其特点:该工具以两个45°斜面进行调整,并通过调整使刀具作径向运动,用螺母压紧。它具有使用方便,掌握容易,体积小,精度高等特点。制造与使用:两个45°斜面要配合好,螺纹 M48×1配合间隙要精密,心轴上的18~(+0.023)槽和▽7滑动
In the craze of the people throughout the country studying the theory of dictatorship of the proletariat earnestly, in the great joy of celebrating the 15th anniversary of Angolan’s constitution, the factory made and used a fine-tuning milling boring tool (Figure 1). Structural principle and its characteristics: The tool is adjusted with two 45 ° bevels, and by adjusting the tool for radial movement, with a nut compression. It is easy to use, easy to grasp, small size, high accuracy and so on. Manufacture and use: two 45 ° bevel to cooperate well, the thread M48 × 1 with the gap to be precise, the spindle on the 18 ~ (+0.023) slot and ▽ 7 sliding
